Did it last year and doing a again this year. Well organised and a lot of fun.
I just take mudguards of my commuter, very lossely a cyclocross but urban commuter and but some knobbly tyres on. What is your bike plan?

I've been mixing my training between road, turbo & some forestry rides around Clocaenog on my crosser, but not enough of either to fill me with huge confidence. I'm pretty sure I'll get around, but it's just a bit too early in the year for me.

I'll be using my Merlin brand crosser 46/36 & 11/32 with tubeless 38mm rear & 40mm up front. Most of my training has been with 11/28 & 38mm Specialized Trigger clinchers.....which have been great.

You're taking mudguards off & I'm putting some on. I've been using a Crud Race Pac Mudguard Set & although initially only bought for the front guard I've found the rear guard fantastic at keeping my arse dry .

How did you do last year & what will you do differently this year?

You seem more serious than me. I meandered round just missing my 12 hour target but had too much kit and spares so soon after the event I bought a frame bag to replace rucksack as I'd seen a load of others had them. More than anything it is the discipline of just using the smaller space though saving the back is extra bonus.
I've done even less bike than last year and no longer rides so will be a very steady initial 150km from me then see if I can push for the final loop round the reservoir.
You've caught me out on the guards - I too bought crud catcher type guards and put them on in place of the full mudguards normally on the bike.

Upon finishing I was in a world of pain & only had negative thoughts of the event, however after a few hours of reflection, rest, food & beer I was in a much better frame of mind. Organisation was great, weather was kind, competitors generous & I finished 30mins inside my target time.
